UC28025DWR Description

Short technical summary and product information.

The UC28025DWR from Texas Instruments is a fixed-frequency PWM controller optimized for high-frequency switched-mode power-supply applications. It offers dual alternating outputs suitable for double-ended and full bridge topologies.

 

Key electrical specifications include an operating voltage range of 9V to 30V and a maximum operating frequency of up to 1 MHz. It provides ±1.5A peak totem pole outputs and features control functions such as current limit, enable, frequency control, ramp, and soft start. The device operates within a temperature range of -40°C to 105°C.

 

This controller is housed in a 16-SOIC package and supports surface mount installation. It is designed for applications requiring efficient power conversion and precise control.

 

Additional features include a 50-ns propagation delay to the output and a trimmed 5.1-V reference with undervoltage lockout. The UC28025 is functionally equivalent to the UC3823 and UC3825.
